The Male Hormone Cycle:
Instead of having a month-long hormone cycle like women, men go through an entire hormone cycle every 24 hours.
Morning: Testosterone is highest
Once he shakes off the fog of sleep, high testosterone makes him more energetic, talkative, aggressive, focused, competitive, independent, impulsive and confident.
Afternoon: Testosterone is in the middle of its cycle
He’s a tad mellower than his morning self, but isn’t going on empty just yet. As a result, he’s still upbeat, driven and focused
Evening: Testosterone is lowest
With testosterone bottoming out, he tends to be more passive, agreeable and low-key, making this a good time to ask him for a favor or other request since he’s more likely to grant it. He may feel tired or fuzzy—especially before he’s had a chance to recharge after work or eat dinner. At this point, his libido hits its lowest point. For some men, this low point is still enough to make them capable of enjoying passionate sex; other men may feel too tired for intimacy or have difficulty maintaining an erection.
Even though men have a daily hormone cycle pattern that repeats the same way every day, their testosterone level can be greatly affected by a variety of activities and experiences such as being under the influences of substances such as alcohol can increase testosterone levels as well as engaging in competitive activities
